An extradural mass extends dorsal to the theca from T3-T6 inclusive, resulting in significant compression of the upper thoracic cord, with impression of subtle increased T2 signal within the cord itself.
The mass demonstrates heterogeneous T1 signal, with areas of intrinsic high T1 signal which appear to saturate fat sat post contrast imaging, very bright signal on T2, with vivid contrast enhancement. DWI demonstrates intermediate restricted diffusion.
Numerous prominent vessels are seen in the interspinous spaces, as well as at the affected levels coursing through the foramina. The adjacent vertebrae are unremarkable, and there is no evidence of direct aggressive infiltration. The remainder of the scan is unremarkable in appearance.
